Jira 7 upgrade 6.3 fails Edited

Hi - I tried to upgrade from 6.4.3 to Jira 7.7. It went well then I stuck on last process, license was too old for service desk warning, and I can't continue. But we renewed license couple days ago for Jira software and applied.

Anyway, I reverted to Jira 6.4.3 to remove service desk completly and try upgrade again. but I couldn't find any place.
